Question

我已经以编程方式创建了自定义属性。它没有在管理面板的产品部分显示。我在创建InstallData.php＆amp;之后使用了以下命令。 Options.php文件：

php bin / magento setup：upgrade php bin / magento cache：clean

之后，我无法在管理员的产品部分找到自定义属性。

代码是

public static void main(String[] args) {
    String v = "Iam8 you64 asjkj125 asdjkj333 heis216s";
    int sum = 0, max = 0, start = 0;
    StringBuilder maxWord = new StringBuilder();
    for (int i = 0; i < v.length(); ++i) {
        char ch = v.charAt(i);
        if (Character.isWhitespace(ch)) {
            max = updateMax(v, maxWord, max, sum, start, i);
            start = i + 1;
            sum = 0;
        } else if (Character.isDigit(ch)) {
            sum += ch - 48;
        }
    }
    if (sum > 0) {
        updateMax(v, maxWord, max, sum, start, v.length());
    }
    System.out.println(maxWord.toString());
}

private static int updateMax(String v, StringBuilder maxWord, int max, int sum, int start, int i) {
    if (sum >= max && isPowerOfThree(sum)) {
        maxWord.replace(0, maxWord.length(), v.substring(start, i));
        return sum;
    }
    return max;
}

private static boolean isPowerOfThree(int sum) {
    // see any from https://stackoverflow.com/questions/1804311/how-to-check-if-an-integer-is-a-power-of-3
    while (sum % 3 == 0) {
        sum /= 3;
    }
    return sum == 1;
}

您也可以使用它，因为我曾经以编程方式创建自定义产品属性。</ p>
